How will the Fed tapering impact investors?

The biggest (expected) news in the market this week is the start of “tapering” — the process of slowly reducing bond purchases by the US Federal Reserve, the organization in charge of maintaining financial stability.
But what does tapering even mean and how does this impact you?
It started back in March 2020. When the market cratered, the Federal Reserve started buying billions in bonds each to stabilize the economy.
That day was yesterday, when the Fed announced plans to start reducing purchases by $15B per month, until it stops altogether by July 2022. What could have been a scary event went better than expected.
Tapering typically leads to higher long-term interest rates (i.e. higher borrowing costs) — which cools down the economy.
Data: In the past four times when the Fed began policies that cooled down the economy (i.e. tapering, increasing short-term interest rates) the S&P 500 was:
Meaning: The market was more volatile in the short term but recouped losses in the long-run — i.e. investors were better off staying invested.
This time — “the question in the mind of the market is 100 percent what comes next” — according to former Fed economist, Roberto Perli (via NYT). And what comes next should worry investors even more…
Next on the Fed’s agenda — increasing short-term interest rates — which could hit the economy even harder.
But increasing rates are also necessary to calm down inflation — which is running out of control. And the Fed doesn’t expect to increase interest rates until tapering is completed.
But that’s a problem for another day. For now, enjoy November-January — historically the stock market’s best months.
